Is it possible to repair this type of FPC cable? I am a filmmaker and have just basic soldering skills and know this type of repair is beyond me. This is from a LCD Touchscreen. Is this cable repairable?

I've never tried this type of repair, but I have pulled apart plenty of FPC cables for analysis (to make sure they were manufactured properly) .
In the past I have been able to use an exacto knife and carefully scrape off the kapton layer (you'll need a microscope), after the power planes are exposed it may be possible to solder them together with another flat piece of metal such as copper tape.
The problem with this type of repair is it may be too high resistance for the current carried by the cable, or the repair could be too large for the space that the cable was originally in.
In my opinion, its not worth it. It will be a difficult repair. Try and get another cable from the manufacturer or buy a used or broken unit and use that cable.
I've encountered this sort of connector a few times. What you want to do is pull upwards on the grey flap on the top of the image (though it could also be the bottom half that flips up, I've seen both ways) and once that's up, it releases the spring pressure on the flat flex and lets it slide out easily.
I'm not sure if there's a name for this sort of connector, but they're common, at least in my experience, in laptops. I think they tend to have a lower profile than other sorts of flex connector, and they are much easier to insert the flex into than friction-held connectors.
The description is basically telling you which side the metallic contacts on the connector are located.
Contacts Top - means that the pads on your FPC need to be facing towards the top of the connector
Contacts Bottom - means the opposite, that the pads on the FPC face downwards
Contacts Top, Bottom - means literally both, there are contacts on both sides, so you can connect either way up.
In the case of the connector you are interested in (Datasheet), the terminals in the connector contact both the top and bottom sides of the FPC, which means that you can place the pads on your FPC on either side - it is up to you which one you choose.
